If the pH of an acid is plotted against the amount of base added during a titration, the shape of the graph is caled a titration curve. All acids titration curves follow the same basic shape. At the beginning, the solution has a low pH and climbs as the strong base is added. As the solution nears the point where all of the H* are neutralized, the pH rises sharply and then levels out again as the solution becomes more basic as more OH- ions are added. 14 The titration curve in Figure 1 shows a strong acid being titrated by a strong base. The re is the initial slow rise in pH until the reaction nears the point where just enough base is added to neutralize all the initial acid. This point is the equivalence point. 12 10 qva point Use the graph and reading to answer the ques tions below on a separate sheet of paper. -bullering regian 1) Define the following terms: titration, equivalence point, end point, titration curve. hall-eg peint 10 Vekm ef ha added (ml 20 30 2) Based on Figure 1, where does the pH begin and whe re does the pH end? 3) Based on figure one, what is the independent variable?
